Le permanganate (MnO 4-) est l'anion des sels de l'acide permanganique.On parle souvent de permanganate pour désigner le permanganate de potassium.. Les permanganates sont notamment utilisés pour la synthèse de produits chimiques, en chimie analytique — titrations volumétriques par oxydoréduction, telles l'oxydabilité ou le dosage de l'acide oxalique — et en médecine — pour

Potassium permanganate is an inorganic compound with the chemical formula KMnO 4 and composed of K + and MnO − 4 . It is a purplish-black crystalline salt, that dissolves in water to give intensely pink or purple solutions. It is worth committing the polyatomic ions to memory, including their molecular formulas and ionic charge. Polyatomic Ion Charge = +1 This is the structure of an ammonium ion. The permanganate (MnO 4−) ion is strongly attracted to the negative charge associated with electrons in the pi-cloud of carbon–carbon double bonds (>C C) of chlorinated alkenes and borrows electron density from the pi-bond (π-bond), which disturbs the carbon–carbon double bond, thus forming hypomanganate diester.

Each oxygen has an oxidation state of -2, for a total of -8. Since the ion has a net charge of -1, then Mn must be +7. Formal charge is As a consequence, very intense absorption spectra in permanganate is obtained and all of the four ligand-to-metal- charge-transfer (LMCT) transitions are observed. However, it must be noted that three out of four peaks happen to arise in the ultra-violet region and only t 1 Roman numeral notation indicates charge of ion when element commonly forms more than one ion. For example, iron(II) has a 2+ charge; iron(III) a 3+ charge.

Se hela listan på courses.lumenlearning.com Potassium permanganate is a chemical compound formed by a combination of potassium ions and permanganate, with a certain proportion and structure (its formula is KMnO4, which is equivalent to a combination of one potassium atom, another of manganese and four oxygen). In the permanganate ion, manganese is in the $+7$ oxidation state, therefore it is a $\ce{d^0}$ ion. $\ce{d^0}$ and $\ce{d^1^0}$ ions don't absorb visible spectrum radiation because there are no electrons to jump to higher crystal field orbitals (or in the case of $\ce{d^{10}}$ ions, there are no free orbitals for electrons to jump to).

I thought that d 0 and d 10 ions don't absorb visible spectrum radiation because there are no electrons to jump to higher crystal field orbitals (or in the case of d10 ions, there are no free orbitals for electrons to jump to).
